National Marine Sanctuary

For more than 40 years our national marine sanctuaries have worked to protect places of historic/cultural, ecological, and natural importance in America's ocean and the Great Lakes.

We are pleased to be working with communities along our Wisconsin coast to apply for the establishment of a national marine sanctuary to preserve shipwrecks in our mid-Lake Michigan region. Watch for updates on this effort. To learn more about NOAA and National Marine Sanctuaries, visit sanctuaries.noaa.gov

The Wisconsin Maritime Museum is currently in our Winter season. Please click here for more information on our hours and submarines tour times. Tours are available throughout the day as needed, and are currently offered five days a week, weather permitting. Tour times vary by season. Allow three to four hours to fully explore both the Museum and tour USS Cobia. Group tours are available anytime with an advance reservation.
